Methods for managing pressure buildup within subsea production equipment using compressible particles

A method for managing pressure buildup within a component of subsea production equipment using compressible particles, the method comprising:

• providing a packing of compressible particles by:
• impregnating the compressible particles into a cross-linked polymer matrix, or
• encapsulating the compressible particles within an elastomeric coating;
• affixing the packing to an interior surface of a fluid-filled closed volume that is defined within a component of subsea production equipment;
• deploying the subsea production equipment within a subsea environment as part of a subsea production system;
• increasing a fluid pressure within the fluid-filled closed volume via at least one of thermal expansion or mechanical straining of the fluid within the fluid-filled closed volume;
• and
• attenuating the increase in the fluid pressure via reversible volumetric contraction of the compressible particles within the packing.

A method for managing pressure buildup within a component of subsea production equipment using compressible particles, the method comprising:

• positioning the compressible particles within a containment area that is defined by a filter screen, a piston, or a diaphragm that enables pressure communication between the compressible particles within the containment area and fluid within a fluid-filled closed volume defined within a component of subsea production equipment;
• deploying the subsea production equipment within a subsea environment as part of a subsea production system;
• increasing a fluid pressure within the fluid-filled closed volume via at least one of thermal expansion or mechanical straining of the fluid within the fluid-filled closed volume;
• and
• attenuating the increase in the fluid pressure via reversible volumetric contraction of the compressible particles within the containment area.
